Folded, Third then third at the waistband, then halved to make a square. My dresser drawer can hold exactly 12 pairs, four piles, three pairs high. I have 13 pair so when I finish laundry, have the 12 pairs that fit. Rotate the piles so that the newest washed move to the back and oldest in the drawer moves to the front.
Might have a problem. But also the moment laundry is done on Saturday morning, I'm at peace for the moment.
